SEO Case Study: How Inogen Alliance Optimized Their Way to 186% Increase in Contacts

The strategy: A resilient, data-driven SEO approach

The Opportunity

Despite Inogen Alliance’s global reputation and deep expertise, their digital presence was not fully aligned with the organization’s stature. They needed a clear content marketing and optimization roadmap to showcase their leadership in environmental, health, safety, and sustainability consulting to the audiences that were actively looking for their solutions.

To solve those challenges, Inogen Alliance partnered with TopRank Marketing to build a data-driven SEO and content strategy that included a content ecosystem to significantly elevate their brand visibility, engage the intent of their global audience, and position their company as the best answer for hundreds of environmental, health, safety, and sustainability search terms.

At TopRank Marketing, we don’t just chase rankings – we engineer long-term search success. For Inogen Alliance, we built a multi-layered strategy that combined technical SEO expertise with audience-first content, ensuring their subject matter authority remained unmistakable.

We focused on three core areas to transform Inogen’s digital presence:

1. Precision keyword targeting

Through deep analysis, we identified the highest-impact keyword opportunities and ranking gaps, optimizing content for the exact terms decision-makers were searching for. Instead of simply targeting high-volume terms, we focused on high-intent queries, ensuring Inogen Alliance reached the right audience at the right moment.

Result: Inogen’s keyword footprint expanded by 178%, driving a surge in high-intent traffic.

2. Content built for search intent

Search success isn’t just about keywords — it’s about delivering content that matches user intent. TopRank helped develop a content ecosystem that built authority in Inogen’s key business segments quarter by quarter. Each piece answered critical industry questions, solved pain points, and provided real value to searchers.

Result: Inogen Alliance secured 55 #1 rankings, reinforcing their leadership in organic search.

3. On-page optimizations (OPOs)

We strategically refined and expanded service and solution pages to strengthen their authority and relevance in search results. By improving structure, internal linking, metadata, and user experience, we helped ensure Inogen Alliance’s site wasn’t just visible — but also engaging and easy to navigate.

Result: Major ranking jumps on high-value keywords, including securing a #1 ranking for a primary service term.
